How do you write 18 as a product of prime factors?
3 Answers
Explanation:
We take 18 and break it down into factors until we reach numbers that are primes.
The prime factors are multiplied together to get a product at the end and together make the answer.
See explanation.
Explanation:
To write a prime decomposition of a number
- Find the lowest prime number
#p# which divides#x# . Write#x# as a product:#x=p*x_1# - Repeat this procedure until
#x_1# is a prime number. - In the final step you can write the product(s) of repeating prime numbers as a power(s).
Here we have:
It is an even number, so we can write that:
Now all the numbers are prime, so the decomposition is complete:
#18=2*3*3#
The product of 2 numbers
#18=2*3^2#
